From mboxrd@z Thu Jan 1 00:00:00 1970 From: Yann E. MORIN Date: Sun, 18 Jun 2017 11:09:40 +0200 Subject: [Buildroot] [PATCH 03/14] toolchain: remove CodeSourcery sh toolchain In-Reply-To: <0fa55d92e86e034d134945a6950229963712102c.1497583686.git.baruch@tkos.co.il> References: <0fa55d92e86e034d134945a6950229963712102c.1497583686.git.baruch@tkos.co.il> Message-ID: <20170618090940.GC2918@scaer> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: buildroot@busybox.net Baruch, All, On 2017-06-16 06:32 +0300, Baruch Siach spake thusly: > Since glibc 2.17, executable link command need not include the -lrt option for > clock_* system calls. As a result, over time less and less software packages > bother to check whether to toolchain needs -lrt. We are now at a point where > maintainers refuse to add this complexity into their build system. This > requires Buildroot to carry patches fixing this issue indefinitely. > > glibc 2.17 is now 4.5 years old. There is no reason to use an older version > with current software. > > This commit removes the predefined profile for CodeSourcery sh toolchain that > is based on glibc 2.16. One may still use the custom external toolchain > support in Buildroot to get this toolchain back, and deal with any build > issues that this toolchain causes. > > Signed-off-by: Baruch Siach Reviewed-by: "Yann E.
